Another person, considered a “person of interest” in the case, has been held on unrelated charges. Louis Perez, 45, was also arrested on unrelated charges. Perez is believed to be one of the last people seen with her and has been arrested on unrelated charges, according to officials.

He has been questioned regarding Killgore's disappearance, but detectives said he was uncooperative.

Perez is an active duty Marine based at Camp Pendleton and is currently in San Diego Central Jail for allegedly stealing an AR-15 assault rifle. Investigators are now classifying Perez as a "person of interest."

"[He is] uncooperative and not completely forthcoming about his knowledge we believe," said Nesbit.

Killgore's father is in San Diego and has been told the latest information about the case, according to officials. Killgore's husband was expected to arrive in San Diego Tuesday night.

Neighbors and friends at Killgore’s apartment complex were shocked at news of an arrest but relieved at the same time.

“I think all of her friends are happy someone is going to be held responsible for this,” said neighbor Christopher Oglesby.”

He said Killgore moved out from Missouri at age 22 to be with her Marine husband.

The Killgores had filed for divorce on April 10, according to court documents.

“Thank you everyone for the prayers and concern," Cory Killgore posted on Facebook Tuesday. "I request you pray for her more then you do for me. I have family and friends for support. She is alone where ever she is."
